That's very much *NOT* the case.

Yes, there is a *fallback* for when somebody doesn't do ndelay() at
all, but that doesn't make it the default.

It's just a "the architecture didn't implement ndelay at all, we'll
work around it".

So stop this idiocy already. About half of what I've seen in this
thread has been pure garbage.
